I am getting below errors
unable to Quiesce guest filesystem errors for vm's and backups are completing with errors.
From other post in forum https://forum.commvault.com/forums/thread/46122.aspx. i knew it is because sp12 treats it as an error when guest file system cannot be quiesced while taking a snapshot.Also i found that
we can add a registry 'ignoreQuiesceGuestErrors' set to 1 to avoid commvault reporting it as an error.
I now need to know where to add registry now,in commserve or proxy servers that are backing up the vc.
